This' invention relates toa copy holder, which enables a linewise displacement of aline pointer on the copyV sheet by push button actuation during-the copying of a typed copy.

The copy holder according to the invention comprises .a rplate for supporting the vcopy, a line pointer, Whichis `verticallyadjustable on thevplate and pivoted to a carrier, fwhich engages vertical rows of pins on a control shaft, to which a limited angular lmovement can be imparted by actuation of a push button, said carrier being subjected at vthe same time to the inuencelot a spring force which ytends to urge lche carrier downwardly.

Another feature of the invention resides in that the control kshaft comprises a plurality `of vertical rows of y.pins .arranged-in pairs of adjacent rows, the Apins -of one yrow of each lpair being spaced in accordance with the line spacing of the copy and the pins of the'other Yrow of each 4.pair-lying between the vpins of the rst row and being angularly offset therefrom.

Y A further feature ofthe invention resides in that a latch entering between the pins of the control lshaft is .provided on the carrier of the line .pointer and is connected by a Bowden Wire to a spring-loaded ratchet mechanism, which is strained during theupward movement of the latch.

'Additional features of the inventionwill be explained with reference to the drawing, which shows an lillustra- .t'ive embodiment kof the copy holder according to the invention.

Fig. 7 is a longitudinal sectional View of the base portion of the stepping device of the copy holder, taken on line VII- VII of Fig. 8, and Fig. 8 is a sectional view taken on line VIII-VIII of Fig. 7. Figs. 3 to 8 are drawn on a larger scale than Figs. l and 2.

The copy holder according to the invention comprises a plate 74 (Fig. 2) for supporting the copy. This plate is axed with screws S4 (Fig. 4) to a housing 8, which carries at its end a guide plate 13 and serves for receiving a control shaft 1. The latter is provided at both ends with journals 2 and 3, respectively. The upper journal 2 is disposed in a bearing 80 (Fig. 5) and extends in a bore 23 through the bottom 21 of the head member 20. That end of the journal 2 which is disposed in the head member 20 has a wing 4, which is guided in a segment-shaped slot 24 (Fig. 6) of the bottom 21 and 2 is subjected to the load-of a spring 25, which is hung `at one end in the eyelet 5 on the lwing 4 yand at its `other end on-a bolt affixed to thebottom 2l. This spring 25 tends always to swingthe control shaft 1 in the direction of arrows a. For this reason the wing 4 will alwaystend to engage the left-hand (when viewed asin Fig. 6) edge of the slot 24. The head member 20 is covered by la cap 29 (Fig. 5), which supports a rotary knob 30. Screws `31, 32 connect the knob 30, the cap 29 and .the head 20 to each other. The heads of these screws are countersunk in the knob 30 and their screw threads are threaded inthebottom 21 of the head member 20. The vhead member 20 is continued by a sleeve-86, which embraces-the top end of the lhousing 8 and termi .nates in a ring .34, which has `notches 87 for receiving -alockingfdevice1-7. The latter-is guided in a cage 88 and `turned through any desired angle with the aid of the knob 30.

As is shown in Figs. 3 and 4, thecontrol shaft 1 com- .prises vertical rows of horizontally vextending pins 6',

which are spaced around the periphery of the shaft. These rows of `pins are arranged in pairs of adjacent rows 6, 7. The spacing of the-pins'of one row, e.g., of the row 6, equals the line spacing of the copy; the pins of the other row 7, which is oiset by a small angle from the row 6, are arranged between the pins of the row 6. Because different typewriters have diierent line spacings, each double row ofthe pins l6 -is dimensioned in accordance with another `line spacing.

As is shown in Figs. l to 4, a carrier 42 is vertically adjustably provided on the guide plate 13. This carrier is connected by a double joint 57, 58 to a line pointer 56, to which a slight vertical vadjustment along a screw spindle 92 `can be imparted by means vof a nut 59. The carrier 42 has two lugs 50, S1, between which a release member -45 is pivotally mountedon the pin 52. A latch 47 entering between the pins 6 is tted in the nose 46 of this release member. During the vertical adjustment ofthe carrier 42 the nose 46 slides in the slot 14 ofthe plate 13. The 'guidance of the carrier 42 is assisted by a cam guide 43. This construction requires slots 49 and 48, respectively, to be provided in the cam guide 43 and the carrier 42 as passages for ythe nose 46. A pulling rope 54 afxed'to the lower end 53 of the release member 45 extends around the pulleys 55 and 19 to a ratchet mechanism 75. This mechanism is mounted between the brackets l64, 65, which are aflixed with screws 44, 44 to the housing 8 and have cheeks 66, 67 through which extends a bolt 568 Vhaving a head 69 and a Wingnut 70 forclamping the ratchet mechanism. The latter com,- prises a drum 76 for winding up the rope 54. This drum is provided with a ratchet wheel 78 and encloses a spiral spring 77. The inner end of this spring engages the stationary bolt 68; the outer end of the spring engages the rotatable drum 76. A pawl 79 is provided for holding the ratchet wheel when the spring 77 is in strained condition.

The cheeks 66, 67 of the brackets 64, 65 are downwardly extended in a tube 71, which is telescopcally disposed in a second tube 72 and permits of a rotation of the housing 8 about the central axis of the tube 71. The tubes 71, 72 are xed in their relative position by a wing screw 73. The tube 72 is provided by means of a lever 93 with a clamp 94, which serves for clamping the copy holder to a table top or the like.

As is shown in Figs. 7 and 8, a base member 35 screwed to the lower end of the housing 8 accommodates a stepping wheel 39, which is secured with a key 40 to the lower journal 3 of the control shaft 1. The stepping wheel 39 is actuated by the push button 81 by means of a Bowden wire 37 and a control pawl 38. A connecting member 36 for guiding this Bowden wire is provided on the base member 35. The push button 81 may be detachably affixed to the keyboard frame of the typewriter. It is only necessary to dispose it so that it can easily be actuated by the typist.

The copy holder plate 74 may comprise a clip 82 for holding the copy sheet and may have some scales 83, 83a, 83b etc. for ascertaining the line spacing of the copy. The number of scales provided corresponds to the number of line spacings to which the copy holder can be adjusted, Le., to the number of double rows of pins 6 on the control shaft 1.

The copy holder described operates as follows: The copy is applied to the scales 83, 83a, 83h to lind out which scale corresponds to the line spacing of the copy. The pair of pin rows 6, 7 which is associated with the scale that has been found is then brought into registry with the latch 47. To this end the lever 91 is depressed and the knob 30 is rotated until the row of pins 6 of the respective double row is in registry with the latch 47. Then the lever 91 is released to enable the locking device 17 to lock the control shaft 1 in its adjusted position. The copy is then clamped with the clip 82 on the plate 74.

The release member is lifted to move the same in the clockwise sense when viewed as in Fig. 3. This causes the latch 47 ,to disengage the pins 6'. Thereafter the release member 45 is moved upwardly, moving the carrier 42 and the line pointer 56 along, until the latter is disposed between the uppermost line of the copy. This causes the spring 77 to be strained. When the release member 45 is then released the latch 47 will enter between the next adjacent pins 6', whereby the line pointer 56 is locked in position. If the line pointer lies in its uppermost position slightly below or above the line, the line pointer can be adjusted with the screw 59 to the desired level.

The linewise downward movement of the line pointer 56 is effected by actuation of the push button 81. The depression of this push button causes through the intermediary of the Bowden wire 37 the pawl or wedge 38 to be advanced in the direction of the arrow b, whereby the stepping wheel 39 and the control shaft 1 connected thereto are rotated in the clockwise sense, when viewed as in Figs. 6 and 8, until the wing 4 engages the righthand edge (when viewed as in Fig. 6) of the slot 24. At this time the pin, e.g., of the row of pins 6 (Fig. 4), which previously supported the latch 47 has left the latch 47 and the next lower pin of the row of pins 7 has entered below the latch 47. The strained spring 77 pulls the carrier down onto this lower pin of the row 7. When the push button 81 is released the spring 25 pulls the control shaft 1 back to its initial position; at the same time the wedge 38 returns to its initial position. During this movement the pin of the row of pins 7 has left the latch 47 and has been replaced by the next lower pin of the aforementioned row 6. During the forward and backward swing of the control shaft 1 caused by a single depression and release of the key 81 the latch has moved from one pin of the row of pins 6 to the next; at the same time the line pointer has moved to the next lower line. This operation is repeated for every shifting of the line pointer to the next line.
